Marvin Jones 687cc211f9 fix(lez): update programs for diff_data's move to Data
Rebasing onto marvin/incremental-updates-1's AccountDiff.diff_data:
Option<Data> change (was Option<Vec<u8>>) needed real fixes, not just a
mechanical rebase: every program's update_from_diff and every
diff_data-constructing call site was still written against the old
Vec<u8> shape. Several sites were doing a pointless Data -> Vec<u8> ->
Data round trip to satisfy the old field type; those now just pass the
Data value straight through. The host-side
execute_update_from_diff/prove_update_from_diff/write_update_from_diff_inputs
in lee/state_machine move to Data too, matching what now flows from
lee_core.

Programs

This crate serves two purposes at once:

  1. Provide one entrypoint for cargo risczero build to build guest binaries used in LEZ in one shot.
  2. Provide access to the built binaries wrapped with Program type.

Binaries

This crate contains binaries taken from sub-directories: one per each program. This binaries are meant to be compiled with cargo risczero build. No other use is intended for them.

Library

You may import this crate as a library but it will only make sense if you enable artifacts feature flag. Enabling this flag will make crate expect that binaries where already built and put in the right place (use just build-artifacts for that).

Why not just risc0_build::embed_methods() ?

Because this will either provide non-deterministic guest build or requires Docker. And forcing to use Docker to build the project is not an option for us especially because we also build Docker images for our services, which would mean we would have to call docker from docker (and this is not really feasible).

risc0_build::embed_methods() works well when you don't need deterministic build or Docker is not a problem. This is the case for our tests and we use it there.
